1 SS Section Polished Concrete Finishing Specifier Note: This product guide specification is written according to the Construction Specifications Institute (CSI) 3-part format. This section must be carefully reviewed and edited by the Architect or Engineer to meet the requirements of the project and local building codes. Coordinate this section with other specification sections and the drawings. Delete all Specifier Notes when editing this section. Specifier Note: This suggested specification is designed for existing or new hardened concrete. Concrete for new construction should be specified under Section (cast in place) for curing, mix design, compressive strength, finish troweling, and floor flatness tolerances. can assist with modification of your existing specification with emphasis on the sections above and other pertinent sections for designing a concrete floor for polishing. Specifier Note: This guide specification is provided as a start point for the design professional. Any modifications to the specification are the responsibility of the design professional. Contact with any questions regarding this product. PART 1 GENERAL 1.01 SECTION INCLUDES Specifier Note: Select StarSeal PS system desired. A.
